如何使用 biblatex 强制在多作者内联引用中换行？

Question

您遇到的问题与并没有直接关系biblatex，而是与 TeX 的段落构建系统有关。因此，与其对引文本身进行处理，不如等到文档的最后阶段再调整各个段落。

一种方法是使用环境\sloppypar，它设置影响间距的各种因素，以便允许通常不好的段落。

\begin{sloppypar}
  ...
\end{sloppypar}

集合的两个因数sloppypar是\emergencystretch和\tolerance。参见

\fussy、\sloppy、\emergencystretch、\tolerance、\hbadness 是什么意思？

解释所有这些是如何工作的。但是\sloppypar为这些设置的值相当大，因此更细粒度的方法是使用环境emergency，如 Heiko Oberdiek 对此问题的回答中所定义：

本地设置 \emergencystretch 的环境

\newenvironment{emergency}[1]{%
  \par
  \setlength{\emergencystretch}{#1}%
}{%
  \par
}

此环境为设定了一个值\emergencystretch，该值可能足以完成工作。首先尝试较小的值，然后根据需要增加。

以下是一个小示例文档，用于展示其工作原理。我添加了一些参考书目项目，但正如您所看到的，它们并不是问题的直接根源。为了看到这一点，我还添加了一个可移动的单词“foo”，它将显示改写的效果。如果您调整边距或单词的位置或环境设置，emergency您可以看到它的全部作用。黑色标记显示溢出的框。
